Weight - Level 3

The weight of an airplane is the force, which
acts vertically downward toward the center of the earth and is
the result of gravity on the airplane.

Just as the lift of an airplane acts through
the center of pressure, the weight of an airplane acts through
the center of gravity (C.G.). This is the point through
which the resultant of the weights of all the various parts of
the airplane passes, in every attitude that the airplane can
assume.
